State Of School Networking Critical For Students’ Future

Last week the Federal Communications Commission (FCC) approved some long-overdue changes to the E-Rate program.  For those of you not familiar with E-Rate, the program, enacted in 1996 under the name “Schools and Libraries Program”, subsidizes broadband and computer equipment for the K-12 vertical and libraries across America.  The program emphasized connecting low-income and rural […]

Network Functions Virtualization Enables Cost-Effective Route Reflectors

One of the concerns I hear from network managers regarding all things software defined networks (SDNs) is the lack of use cases for the new technology.  It seems the technology promises to solve so many problems that it’s hard to understand where to start.  Network Functions Virtualization (NFV) is no different.  Lots of possibilities, but […]

Internet of Things Shifts Computing From the Cloud to the Fog

Mark Twain is rumored to have once said, “The coldest winter I ever spent was a summer in San Francisco”. And if you’ve ever been to San Francisco any time of the year, you’ll know that one of the distinguishing characteristics of the city is how cool, damp, and foggy it can be.  I’ve been […]

IP Video Surveillance a “Deadly” Application for Network Virtualization

It seems in the technology industry we’re always on the lookout for the “killer application” to take something that’s new and make it mainstream.  The best example of this was, of course, Lotus 1-2-3 and its role in the Windows interface becoming the de facto standard it is today.  After that, the floodgates opened and […]

World Cup Creates a Messi Environment for Network Managers

There’s no question that recreational traffic plays havoc with business networks. Between the PGA Masters, NBA March Madness, MTV Music awards, YouTube, and other events, network managers are always struggling to block recreational traffic. This week, of course, viewers across the globe are using the corporate network to find out how Argentina and Lionel Messi […]

More Education Is Needed to Move the SDN Needle

As an analyst, it seems like I’ve been talking about SDNs forever. It’s hard to have a conversation with anyone about anything in networking without “SDN” popping up. Every time I speak on the topic, the rooms are packed. Blogs on this topic are always well-read, and almost every network vendor has some kind of […]

Attention Network Managers: It’s Time To Shift to a Software-Defined WAN

I’ve done a number of blogs recently on the topic of WAN evolution.  In them, I tried to make the case that a software-defined WAN was a good alternative to a traditional WAN.   I’m changing my stance on this now and stating that the software-defined WAN should be the only type of wide area network […]

Will Virtual Overlay Networks Cause “Network Sprawl”?

It’s hard to have any discussion with any networking person today without the term “Software Defined Networks” (SDNs) coming up within the first five minutes. However, what I’m starting to see are discussions occurring a level down from the über term of just “SDN”. Topics like Network Functions Virtualization (NFV) and programmability of the network […]

Network Fabric for Healthcare: A No-Brainer

The concept of a network fabric has been around for a few years now, but deployments have been spotty.  One of the reasons for this sparseness is that it’s tough to come up with any kind of ROI around a network upgrade, particularly in the data center where you’re talking about pricey infrastructure. To combat […]

Charles Darwin Would Have Embraced The Software-Defined WAN

It was Darwin who claimed that it’s not the strongest that survive, but the species that are the most adaptable to change. The world of networking is no different. The network, particularly the WAN, hasn’t changed much over the past couple of decades, as there really wasn’t a requirement to change, but there has been […]
